NHC outlook text (verbatim)

For the North Atlantic...Caribbean Sea and the Gulf of America:

Active Systems: The Weather Prediction Center is issuing advisories on Post-Tropical Cyclone Isaias, located inland over Tennessee.

Eastern Tropical Atlantic: An elongated area of low pressure centered about 100 miles southwest of the Cabo Verde Islands is producing a large but disorganized area of showers and thunderstorms extending from near those islands southward for several hundred miles.  Some development of this system is possible during the next couple of days while the low north-northwestward before upper-level winds become too strong for development by midweek.  Very heavy rainfall is also possible during the next few days over portions of the Cabo Verde Islands regardless of whether the system ever becomes a tropical cyclone.

* Formation chance through 48 hours...low...10 percent.

* Formation chance through 7 days...low...20 percent.
